According to the present inventions-these lvaried requirementsaresatisi'ied by the provision ofy a glass containerfor `Isupportinglaninverted bottle and having a sumpin .combination with an insert ofnonfmetallic. materiahsuch-.asgbakeflite or a material havingsimilarlproperties, for cooperation with `a plunger constructed `andmounted in a particularly 4effective nranner. This constructionisespecially satisactoryfwhen employed 'in combination with ,certainyotherfea# tures hereafter described in detail.- Bythe prof vision .of raglass containerthere.isproduceda very `attractive dispenser,4adaptedjfto pleasingly glass alone.

Another feature ofthe invention .residesin an improved dispenserconstruction including an improved top and a plunger carried withthe'toptand cooperatmg with the insert :to-dispense Vliquid from thesump. The entire structure is simple and inexpensive tomanufactureandyeasyto assemble, besides being readily laccessiblefor cleaning andproviding .a minimum ,of surfacesvand spaces for the ,accumulation ofldirt and,y germs.

Other features .of the; invention', including cerf ltain specicimprovements, and other advantages, will become apparent in connection;with the following detailed description of .onepreferred form ofmvnvention, reference :being had'toftheface eempanying drawing, wherein:'1

In the drawing, there is shown at 1 a container foriiquids including awall 2, bottom 3, sump 44, andsbase 5. In order to accommodateaninverted-bottle 6 and at the same time make provisionfor. a short,noni-drip spout, such as will i be hereafter .described in detail, thewall 2 is preferably y.generally rcircular but has an oiset por.-tionr'l forming ya Vwall of the lsump liwhich, is

also offset. The container 1 may preferably .be y

formed `as lan integral cast glass unit,V wherein r thexbottom 3 of thereservoir slopes slightly towardthe sump 4 and the base 5 is a flaredcon,-` tinuation of wall 2,y though these portions ofthev containermaytake other ,desired shapes. Rubber .padszS may be secured to the:bottom of .base 5,A in any suitable manner, to form Ia cushionybectween the .container and any flat surface `9 upon which itis adaptedto stand. i ,e

I-The top 10 of the .dispenser may advantageously beprovided with agroove l1 iormed between flanges 12 and. 13 and adapted to .receivectheupper. edge of wa1l277 about its entire perimeten Ifidesired, spacedfeet 14 may be formed on .the top, within,- the groove, to rest on theupper .edge ofithe glass in` [order to prevent the glass from becomingwedged` in the groove. However; while` a .particularly .eifectiveconstruction may be achieved in this manner, .one'of these flangesmightpbe Yomitted.,if desired, or some other arrangement vmight beemployed for the purpose. indicated. Theflanges 12 and 13 and feet 14arefpreferably so arrangedcthat air mayenter the interior .of the.container by passing between the flanges .and wall 2 between the feet.The top 10l may 'have an annulares'haped portion 15 forme. ingiacen'tral opening to receive the neck of an inver-ted .bottle .6, and ashouldered portion 16 for seating a -ring 17'of rubber orothercushioning material upon which thebottle is adaptedto rest. i isAlsosecuredfto. and preferably :formed intesrallwith i.tlietcm A1,0there may-be provided. a cylindrical sleeve 20 `forming a guide for atube 2 1c onv,eniently formed o-fmetal and adapted to carry a meneerelement 22 for kdisplacing liqu frornfthe'sump. 1'Iube21 serves toconvey theliqlld displaced to a glassor kother receptacle heldibelewvthe meuth 23 ef the tube. The tube .2.1isrece'redwithin the .Sleeve 20and may be rrevided with e key :Medepted t0 Slide in a kev- Way 25for-med, at-one side of the sleeve, to prevent the tube 21 from turning.A coil spring 26, for raising thetube after it has been depressed,mey-surroundrthe tube ;2.1 and lie snugly between the semeand the insidewall of sleeve 20, resting on shoulder 27 formed on the top 10 andabutting against shoulder 28 on the tube. The lower end of tube 21preferably extends downwardly into an opening formed centrally ofshoulder 27, and has a sliding fit with the walls of the opening.

Through this construction of the top 10 provision is made not only forsupporting an inverted bottle carrying a relatively large supply of theliquid to be dispensed, but also for a simple and effective mounting ofthe discharge tube and plunger construction in the top of the dispenser.Furthermore, the top 10, when composed of metal may be cast, pressed orotherwise formed -asasingle piece, thus greatly simplifyingmanufacturing operations. l may be removed from the container 1 in amoments time when the device is t be packed for shipping or is to becleaned after use; i

Fitted into and lining the sump 4, andpreff erably removable therefrom,there is provided a generally cylindrical memberv or insert 30having anopening 31 at the side facing the main portion of the containersurrounded by Vwall 2.

and having the balance of its periphery closely adjacent to or incontact with wall 7. The bottom 32 of the opening 31 is preferablyadapted to lie at the level of the bottom?, of the container. f, Theopening 31 may extend to the top of the inem'- ber 30, or if preferred,may extend upwardly merely a distance sufcient to'permit liquid to flowinto thesump. In either case the wall of the insert above the level ofbottom 3 will preferably form the greater portion of a cylinder. Theupper edge 33 of member 30 preferably abuts against anges 13 on top 10.Ears 34 formed on Ithe member 30 serve to maintain the `member againstturning, through abutment with wall 7.

The plunger 22 may have al tubular portion 35 and an enlarged lower endportion 36 'adapted'to have a sliding fit in the member 30,- the sidewalls 37 of which actas a guide for the plunger. For securing theplunger 22 to tube 20 a threaded sleeve or nipple 40 may be securedtotherplungerv in any convenient manner, as by screw threads or by beingembedded in the material of the plunger, and it may be adapted to bescrewedinto threads 41 atthe lower end of the tube 20. `Abut ment of theupper end 42 of plunger`22 against a surface on the top serves to limit.upward movement of the tube andplunger under the action .of spring 26,thev plunger preferably being of such length and so arranged that whenit is in normal, raised position no other Vparts of the displacingmechanism need vbeL in contact with the liquid. VIf desired thearrangement may be such that theplunger is not completely immersed inthe liquid even when depressed in the manner. to be explained. Inassembling the construction it is merely necessary to insert the spring26 and tube 21 in the sleeve 20 and screw the threaded sleeve V40k intothe tube. The cover' 10 may then be put in place after the memberv30 hasbeen slipped into the container 1.v f

The member 30 and the plunger 22 may pref erably be formed of bakeliteor the like, or some other suitablenon-metallic material such as hardrubber. Through this construction not only is accurate measurement oftheliquid secured but the imparting of a metallic taste tothe same isavoided and at the Sametime a glass container may be employed both forits attractive appearance and relatively low cost. Moreover, the member30 besides serving as anac'curate measuring sump acts as a guide fortheplunger22, as mentioned. 1 Furthermore, lthe, parts f are fall simpleand inexpensive to manufacture, few in number and easily assembled.

The upper end'of the tube 21 adjacent the mouth 23 is preferablyconstructed so that the lip 45 does not extend horizontally to anyappreciable extent but lies generally in line with the front wall of thetube 21, while the portion 46 overliesvtheupper end of thetube andextends outwardly beyondthe lip,.providing curved surface 47 fordirecting the ow of the liquid. Such aspout is particularly effective,for preventing drip, especially apt to occur with Syrups, and may Lbeemployed to good advantage with the off-set sump arrangement, whichpermits the short spout to lie adjacent the line of the front wall ofthe dispenser. Moreover, this construction providesl for delivery of theliquid in a di- "frection outwardlyof the device, so that the glass p,into which the fluid is to be delivered need not be held close to oragainst the device, thus avoiding chipping of glasses.

The operation of the device will no doubt be apparent lfrom the abovedescription of its construction, but it may be here briefly summarized.Upon .placing a bottle in inverted position on the device'as sho-Wn theliquid will ll the container 1 up to the level where it seals the mouthof the bottle, whereupon by depressing the tube 21 and plunger 22A toits'maximum extent of travel a definite-v quantity of syrup will beexpelled through'mouth 23. In this manner, the accuracy of measurementis insured by reason of the fact that on the one'hand the level ofliquid in the container is always constant as long as there is someliquid in the inverted bottle, due tothe dipseal, and on the other handthe plunger cuts off or segregates an exact quantity of liquid from thebulk rin' thecontainer before the dispensing action begins. There is`thus' always displaced from within 'the plunger the same vamount ofliquid. When the device is empty and an inverted bottle is put in placethe level of the liquid automatically adjusts itself, and when thatbottle is just empty the attendant need only replace it with arfull one.i The possibility of error in operating the device is accordinglyreduced to a minimum.

While the invention has been described in 'connectionV with andisparticularly adapted for use with an inverted bottle, it will beunderstood that certain of the features disclosed are similarlyadvantageous when the liquid is supplied to the container in othermanners.
